or tell me the difference between step motor drive and general stepper motor drive for dance table lamp
1DMX512 protocol introduction the communication between dance table and console follows the DMX512 protocol. DMX512 protocol is the American Association of theater Technology (USITT) a lighting console for data transmission and lighting equipment agreement on 1990 issued revised, including all aspects of electrical characteristics, data protocol, data format and content. The DMX512 electrical features are fully compatible with the RS-485, including the choice of drive / receiver, line negative, and money
Stage lighting as an important part of many stage equipment, can achieve such complex functions as changes, lighting colors, background patterns, space positions, effects and other functions. Stage lighting is substantial control and coordinated control of multiple stepper motors, the author of this paper stage light mechanical structure of cooperative enterprises based on existing introduction there is a huge difference in speed, positioning accuracy, inertia control of 16 stepper motor technology research and system design of cooperative control.
Stepper motor as an actuator, because has the advantages of high precision, small inertia and reliable work, and can realize fast open-loop control with high precision, and is widely used in the stage lights in motion control system. The system requires the stepper motor to high speed and accurate operation of stage lights control, to ensure that the stepper motor in the step and but write under the condition of running to the specified location to the fastest speed, the speed control of stepper motor and stepper motor coordinated control is proposed high requirements.
